HENRY C. GASSEL, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 172,088, dated January l1, 1876; application filed December 11,1875.

To all whom it may concern:

Be it known that I, HENRY C. CAssEL, of Philadelphia, Pennsylvania, have invented an Improved Stove, of which the following is a specication:

My invention relates to certain improvements in the construction of stoves of clay; and the objects of my invention are to facilitate and improve the construction of stoves of this class, and to afford an extended airheating surface.

These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which Figures l and 2 are vertical sections of my improved stove; and Figs. -3 and 4, detached yiews, illustrating some of the features of my lnvention.

A is the top, B the bottom, I) D the front and back, and E E the opposite sides of the stove, all composed of baked clay, terra-cotta, or other equivalent material, which will heat the air Without imparting to it that objectionable character' which is imparted-to air brought into Contact uith' metallic surfaces. The front, back, 'and sides of the stove are composed of blocks a, on the inside of each of which are inclined flanges b, so that when a number of the blocks are placed together to form one of the walls of the stove, a dovetailed recess will be formed at the joints. These recesses are filled with cement, x, which, upon the application ot' heat, becomes hard and binds the blocks firmly together. The space at the back of each block a, inside the flange b, may also be filled with the cement, in order to render the wall of the stove more homogeneous.

. The cement used should be ot' a compressible nature, so that its expansion by heat shall not disturb the anges lof the blocks.

I prefer to employ a cement composed of Y about equal parts of clay, gravel, and bran, the latter element, in this case, being compressed when the former elements are expanded. Any compressible cement may, however, be used.

Within the stoveis, in the present instance,

an air-heating chamber, F, cooking-oven G, and fire-place H, an ash-chamber, I, being formed in the bottom of the stove.

The casing S, which incloses the chamber F, oven G, and fire-place H, is made of a material similar to the casing of the stove, so that air may be heated in the chamber F to be used in addition to that radiated from the surface of the stove, for heating the room in which the latter is situated; or it may be carried oft' through a pipe, d, (shown in dotted lines, Fig. 1,) to an adjacent room.

casing of the stove, and make the entire circuit of said [lue around the oven G and chamber F, and finally, after passing under the lower edge of an angular' partition, 7L, (see Fig. 3,) escape from the opening into the exit-pipe.

If desired, the oven G may be dispensed with, and the heating-chamber F extended entirely to the tire-place.

It will be evident that a stove of any desired size can be readily built up in the manner described, and can be easily repaired, while ample facilities are afforded both for heating air and for cooking, the produts of combustion passing over such an extended surface, before escaping, that their heating properties are fully utilized.

I claim as my invention- 1. A stove the casing of which is composed of a series of clay blocks, a, having inclined fianges b, all substantially as and for the purpose set forth.

2. The combination of the tire-place H and exit-opening i of the stove with the due g,

formed between the inner land outer oasin'gs In testimony whereof I have signed my of' the stove, and communicating with the renaine to this specification in the vpresence of place through the opening f, all as specified. two subscribing witnesses.

3. The oven G, provided with a metal bot- HENRY C. CASSEL. tom plate, e, and interposed between the re- Witnesses: place H and heating-chamber F, having walls HARRY HOWSON, Jr., of clay, all as set forth. HARRY SMITH.
